President Donald Trump has dominated the nation’s political landscape in his first two years in the White House, and early results from today’s NBC News Exit Poll suggest that he shaped today’s congressional elections.

Two out of every three voters say Trump was a factor in their House vote, with 26 percent saying they cast their vote to express support for the president and 38 percent saying their vote was to oppose the president. The remainder — one-third of midterm voters — said Trump’s performance as president was not a factor in their House vote.

Powered by a suburban revolt against Trump, Democrats reclaimed a majority in the House, and scored a string of upsets in doing so. By 6:30 a.m. ET on Wednesday, the party had picked up 28 seats in the House, more than the 23 needed to take the majority, with many West Coast results still outstanding. Fourteen seats remained uncalled.

Republicans successfully defended Senate seats in Texas and Tennessee, while also picking up seats in Indiana, Missouri and North Dakota. After an overnight nailbiter, Democratic Sen. Jon Tester won re-election in Montana, NBC News projected Wednesday.

In gubernatorial races, Democrats made some key gains even as Andrew Gillum in Florida was defeated and Stacey Abrams in Georgia was trailing. Democrats won in Wisconsin — defeating Trump ally and former Republican presidential candidate Scott Walker — as well as Illinois, Minnesota, Colorado and Nevada.

In the Alaska gubernatorial race, which was considered "too early to call" in the early hours of the morning Wednesday, Republican Mike Dunleavy is the apparent winner, NBC News projects. In the Connecticut gubernatorial race, which was considered "too close to call" overnight, Democrat Ned Lamont is the apparent winner, NBC News projects.

Nationwide, 45 percent of voters report that the tax changes have not impacted their personal finances, while 22 percent say their finances have been hurt by the changes.

The exit poll also shows that voters in higher-income households are twice as likely as voters in lower-income households to report that tax law changes have helped their personal finances. Seventeen percent of voters with annual household incomes under $30,000 said their personal finances had benefited, compared to 34 percent of those with annual household incomes of $100,000 and higher.
